I just got a JVM 205H ,used ,, but the footswitch on 1 &2 stay blue and I cant seem to switch to the green yellow or red modes . I have the manual but I cant seem to find anything about a blue led on the footswitch. I tried to do the reset on both the head and the footswitch but the blue light and the problem is still there . anyone whats up with that?
Sounds like the foot switch is bad. It's not syncing with the amp.
The Marshall owners manuals leave out a lot of information., I learned about my amp just by playing with it.
